Rotary Drilling Rig XCMG XR220D adopts single layer main winch, which effectively solved the wear problem and improves the service life of steel rope.
·The infrared camera is convenient for operators to observe the steel rope of main winch in the cab at any time.
·Multiple configurations can be customized according to the requirements, like outrigger cylinder, automatic slewing, etc.
·It adopts imported electric controlled Cummins turbocharged engine (Euro Ⅲ), which has strong power and meet the requirements for energy-saving and environmental care.
·The hydraulic system adopts extreme power control and positive flow control, which makes the hydraulic system more efficient and more energy-saving.
·The patented parallelogram luffing mechanism can cover wide work areas; the drill mast is designed as box structure made of high strength materials, which ensures the boring precision with higher rigidity and strength. And all the articulated points adopt lubrication-free bearings.
